Thanks for reply, I did other tests and I found that having empty 
harddrive boot from cdrom correctly also with omvf, the problem seems 
that not cosider boot option at all.
I did also few tests about ovmf and if I remember good is the first time 
I try to boot from cdrom on domUs with harddrive not empty, other time I 
did it only for system install, then is probable that the is present 
also in older xen and ovmf versions.
